perf(ivy): use instanceof operator to check for NodeInjectorFactory instances (#33082)

We used to have a custom version of the NodeInjectorFactory check that was
supposed to be faster to the direct usage of the `instanceof` operator. This
might have been the case in the past but the recent benchmark shows that using
`instanceof` speeds up the `directive_instantiate` by ~10%
(from time getting from ~340ms down to ~305ms).
